<P><B>Description:</B>
</P>
<P>Set the dielectric constant for Coulombic interactions (pairwise and
long-range) to this value.  The constant is unitless, since it is used
to reduce the strength of the interactions.  The value is used in the
denominator of the formulas for Coulombic interactions - e.g. a value
of 4.0 reduces the Coulombic interactions to 25% of their default
strength.  See the <A HREF = "pair_style.html">pair_style</A> command for more
details.
